On the other hand if someone IS walking in that area, for sure that's the more hazardous area and so they'd want access to a railing.In general, ropes do no make very safe handrails because of their obvious lack of rigidity - better than nothing but not as secure as a solid material. Our code states that the handrail must be “graspable” and 1 1/2″ from the wall, which this meets. The height of handrails must be installed 34 inches - 38 inches from the upper surface of the handrail to the surface of the tread. Abstract: Stair walking is an important functional movement task that may require considerable amounts of muscle strength/power. Handrail size is now consistent between all codes and standards: 1-1/4″ to 2″ diameter or provide Equivalent Graspability. off the plane of the stair tread nosings. M.S. [7] "The Elimination of Unsafe Guardrails, a Progress Report," Elliott O. Stephenson. 505.8 Surfaces: Handrail gripping surfaces and any surfaces adjacent to them shall be free of sharp or abrasive elements and shall have rounded edges. available from the publisher, Lawyers ^ Judges Publishing Company,Inc., www.lawyersandjudges.com. Continue reading at GRASPABILITY of HANDRAILINGS or select a topic from the closely-related articles below, or see the complete ARTICLE INDEX. Definition: Graspability of a handrail refers to the ability to get a secure hold onto a handrailing whose purpose, after all, is both to guide a walker along a stair or other surface and to prevent or perhaps to interrupt slip trip and fall hazards. We include descriptions & definitions of graspability for handrailings, and we illustrate safe and unsafe, graspable and not-graspable handrailings in sketches, photographs, and building code citations. The expectation is that the user does not have to release the handrail to continue to the next flight of stairs. I thought about trying to be cute and make up a cheap wood handrail with normal brackets (3 screws) to pass inspection. And if the "handrail" is soft, flexible, or even floppy rope, that loss of rigidity addes to the hazard as when grabbed by someone who is having trouble walking or who is falling, that wobble and insecure grip can certainly contribute to a fall. The "stair rail" above is not just too big, not graspable, it's also too low. In that circumstance, an improper or unsafe railing is in one sense, worse than had there been no handrailing present at all, since in the latter case a stair user will have observed that there was no railing and may have been inclined to move more slowly and with greater care without that security, just as we are not inclined to step to the very edge of a tall balcony if no railings are installed on its perimeter. Our sketch is from Figure 505.5 of the Florida Handrailing code which states: However it's up to the local building officials to interpret the building codes and to tell you what they require. Many deck handrails improperly consist of 2"x 6" lumber or decking. Is 2” PVC piping allowed to be used as a stairway handrail in a school building? The streamlined design is modern and timeless. Two age groups were tested: young (20 to 45 years) and elderly (59 years and over), with a total of 35 subjects. Apologies for the delay. This article series explains and illustrate the requirements for graspable handrails & railings used inside or outside buildings, including guardrails, hand railings on steps and stairs, and stair rails or stair guards for both interior and exterior stairways. We've moved this to a separate article. 7/26/90 is very often cited by other sources for good design of stairs and ramps etc. They are great for homes by providing a helping hand for family and friends to maneuver around your outdoor space. While graspability of handrails naturally focuses on the profile or shape and dimensions of a handrailing, the spacing of the handrail from the wall, its height, continuity, and other features also will interfere with the ability of a person to securely grasp a handrailing when she wants to or needs to in an effort to prevent or arrest a fall. A graspable rail should not be smaller than 1.25″ or greater than 1.875″ in diameter. As you can see from our model's hand on top of the railing, the width of this particular rail, roughly 6", is too great to be grasped and held on-to should a stair fall occur. Beautiful, this handrailing reflects the Moorish affection for water. Our friend Asta S., visiting el Nigromante Art and Cultural Center in San Miguel de Allende, Mexico, is illustrating the extent of this oversized stair rail - just compare the size of her hand to the railing size. 505.9 Fittings: handrails shall not rotate within their fittings. Stair handrails and guardrails safety #4. But when the railing meets the wall along the upper stairway side the situation changes. A non-graspable handrailing in this condition will deny the stairway any opportunity to arrest the fall, thus contributing greatly to the fall's extent and severity. At this point (above) the handrailing is no longer graspable. New York, NY 10012-2586 The intent of a handrail is to provide a handgrip for people using a stairway. GRASPABILITY of HANDRAILINGS at InspectApedia.com - online encyclopedia of building & environmental inspection, testing, diagnosis, repair, & problem prevention advice. Handrails should be graspable, continuous and smooth. The next three images depict graspable handrails: The three images directly above depict graspable handrails. Ramps, Runways, Stairwells, and Stairs, Section 1626. We think it is more dangerous on the central pillar than on the outer wall where the tread is widest. Edges shall have a minimum radius of 0.01 inch (0.25 mm). Handrails with a perimeter greater than 61/4 inches (160 mm) shall have a graspable finger recess area on both sides of the profile. Original source: osha.gov/Publications/ladders/osha3124.html. Our photo immediately above shows use of a rope or cable "handrail" at the Pyramid of the Sun in Mexico. 26 no. Volume 19, Issue 5, pages 678–686, October 2009. [32] Steps and Stairways, Cleo Baldon & Ib Melchior, Rizzoli, 1989. MAV appeared to be highly dependent upon knee and ankle power and to a lesser extent on joint moment and range of motion. The 6004 Graspable Handrail is one of those options. Railings of this design are not approved by any of the model building codes. Guidelines for Undergraduate Theatrical Productions and Special Events, CUE40303 Certificate IV in Live Production, Theatre and Events (Technical Operations), How to Build Theater Stairs, an Illustrated Guide, HOME INSPECTION EDUCATION COURESES (Canada), HOME INSPECTION EDUCATION: HOME STUDY COURSES. Handrails with a perimeter greater than 6¼ inches (160 mm) shall provide a graspable finger recess area on both sides of the profile. Yet in some locations such as the stone tower shown below, not much more than a rope even fits in the walking space. If a deck or patio is 1.5 metres above a flat lawn, then the height someone could fall is obviously 1.5 metres. The finger recess shall begin within a distance of 3/4 inch (19 mm) measured vertically from the tallest portion of the profile and achieve a depth of at least 5/16 inch (8 mm) within 7/8 inch (22 mm) below the widest portion of the profile. Seventeen healthy elderly women (age 72.4 ± 6.4) were tested for MAV, maximal multi-joint counter movement jumping (CMJ), and maximal single-joint isokinetic/isometric muscle moment. [38] Uniform Building Code Stair Specifications: UBC 1003.3.3.6 1997 or later specify handrail requirements, railing heights, rail widths, baluster spacing, stairway types, and guardrail specifications. P. Aagaard, "Biomechanical determinants of maximal stair climbing capacity in healthy elderly women", Scandinavian Journal of Medicine & Science in Sports Meets residential code requirements for stair hand rail sizing; requires a hand rail when used on stairs in commercial settings.

Please see HANDRAIL CONTINUITY. (The 2-inch handrail is allowed by all U.S. building codes.). The railing is all aluminum and made by Westbury and available in matte or gloss (matte shown). Above we show photographs of more non-graspable handrails that are unsafe: at Carnegie Hall in New York City, and just above, demonstrated by Asta S. in San Miguel de Allende, Mexico. [39] Teruo Uetake & Masahiro Shimnoda, Experimental Study on the Grip and Hold Strength for Staunchions and Handrails in Buses", J. Here is a quick list of related guardrail or railing safety SNAFUs: We find a surprising number of handrailings that the installer must himself never have tried to grasp as they are so close to the wall that grasping is impossible. Series 150 is a 2" wide top rail for with easy-to-grasp design for DesignRail®. U.S. Department of Labor S. Hyde, Jon R. Abele, ISBN-13: 978-1-933264-01-1 or In short, as we demonstrate here, a simple 2x4 or 2x6, placed on edge along a stairway is not a graspable railing and so is not safe. Some (not all) codes allow handrails that have an overall perimeter greater than 6 1/4", most commonly to permit use of 2x lumber to construct handrails. Thanks, John [by private email] 2016/03/21.

Telephone: (212) 777-0062 (must be able to be grasped), Round rails: between 1.25" and 2" in diameter, Metal ogee shaped: <= 2.25" across widest dimension, Wood oblate shaped: <= 2.25" across widest dimension, Rectangular shaped: perimeter must be between 4" and 6.25", Perimeter larger than 6" must have a graspable finger recess (see details at the, Location: Handrailing location: too low, too high along the stairway, Missing: Handrailing is missing where required, Obstructed: Handrailing obstructions: interruptions, blockages to access, Shape: Handrailing shape: profile cannot be securely grasped, Size: Handrailing size: too big or too small to grasp comfortably, Spacing: Handrailing spacing: too close to wall to grasp, too far from wall projecting into stair passage, Strength: Handrailings are not strong enough to withstand loads of a person holding-on or grasping when falling, Surface: Handrailing surface: icy, sharp, splinters, Winder or curved stair blockage: handrailings should include features to prevent people from walking along the portion of angular stair treads that are too small and thus unsafe. While it is readily apparent that a loose, broken, or defective guardrail on a deck, balcony, or landing can contribute to or even cause a bad fall, we sometimes find that the role of the stair handrail in stair fall injuries is underestimated or missed entirely by people investigating such accidents. grooves help but don't eliminate the hazard - for oversized stair rails simply can't be grasped securely. construction. At the start of a fall up or down stairs, people will drop packages or even throw them into the air in the process of trying by instinct to grab onto a railing. A beautiful complement to your railing system is a hardwood handrail.

Abstract: An experimental study was performed investigating the influence of handrail height on the ability of stairway users to generate stabilizing forces and moments, with the aim of improving stairway safety by developing better handrail design standards. Can i use a 2x2 for a graspable handrail in NJ? 200 Constitution Avenue, NW, N-3101 Below are additional excerpts from the IRC, IBC, and Florida handrail codes: The non-circular handrail profile shown above is illustrated in the Florida Handrail code at 505.7.2. where the additional details are specified: 505.7.1 Circular Cross Section [handrailings].Handrail gripping surfaces with a circular cross section shall have an outside diameter of 1 1/4 inches (32 mm) minimum and 2 inches (51 mm) maximum. The following opinions derive the author's experience in building stairs, inspecting stairs in and at buildings, in researching stair construction practices & building codes, and in the occasional assistance in the investigation of stair falls. A handrail made out of a 2x6 set on edge and run along a stairway also cannot be grasped. Telephone (202) 693-1888 or The Best Vinyl Fencing, Railing and More to Accent Your Home. One of the most frequent fall hazards we encounter are home-made railings that are too small or too large to grasp, or handrails that do not permit continuous grasping along their length. But an improperly designed or installed handrail is likely to be discovered, and will contribute to the extent of injuries suffered by someone who slips, trips, or falls when using the stairs. All of these conditions can contribute to a fall and to an injury along a stairway. L. Puggaard, Two age groups were tested: young (20 to 45 years) and elderly (59 years and over), with a total of 35 subjects. Washington, DC 20210 Group 1. However in these larger sizes, the handrail must have a thumb and finger groove; Some older codes may permit the 2x6 handrail profile at far left in the illustration below, but as of 2009 the handrail needs a groove on both sides. E-Mail: ADA (Americans with Disabilities Act), Public Law 101-336. Please see the following stair code articles: We moved this discussion to a separate article now at HANDRAIL GRASPABILITY DEFECT PHOTOS. This handrail might help to steady someone walking up or down the stairs as one can place a hand on the railing. Human Ergol., 35: 11-19, 2006.

These examples of mis-using 2x lumber as hand railings or stair railings are important because it is so common to find them on exterior stairways. 8 no. 26 no. Ability to generate forward/backward forces and forward/backward moments increased linearly with increasing handrail height. [19] Arts, Crafts, & Theater Safety (ACTS), 181 Thompson Street, #23 The stair railing below is attractive but like the full-scale 2x6 railing above the rail below is still hard to grasp, even with thumb and finger grooves because it is just too wide. Or use the SEARCH BOX found below to Ask a Question or Search InspectApedia. Above, the thumb is pressed against the vertical side of a 2x6, relying on friction alone for security - there is no mechanically-locking grasp of this railing - it is unsafe. I don't think codes specify materials, John, rather dimensions, strength, etc. When you attach the stair handrail / handrail brackets to the wall, make sure that they are secured with … An unsafe handrailing may go unnoticed for a long time, even years. All subjects showed a strong linear dependence on handrail height in generating stabilizing forces and moments. In addition, where the railing abuts a vertical surface (my middle two fingers in the photo) the user cannot even latch fingers around the outside of the "railing" - making it virtually useless. (must be able to be grasped), Round rails: between 1.25" and 2" in diameter, Metal ogee shaped: <= 2.25" across widest dimension, Wood oblate shaped: <= 2.25" across widest dimension, Rectangular shaped: perimeter must be between 4" and 6.25", Perimeter larger than 6" must have a graspable finger recess (see details at the.

We have had one quote which has been accepted by the Diocese and our architect but the cost in 2008 was £2270+ Vat. One of my daughters fell down these curved stairs at the Galleria shopping mall (Poughkeepsie, NY) where the triangular tread hazard was combined with a beautiful, architect-designed handrail that was about 8" in diameter (photo at left, red arrow) - she was unable to grasp it as she was falling. Watch out: No model building code and no other building code that we have surveyed permitted 2x6 or even 2x4 handrailings installed "on the flat" as a safe graspable stair handrail system. Below we show how Intercam, a bank in Mexico, solved the a different problem: affixed at a normal distance from the wall, the handrail would be out of reach due to the presence of an antique and very wide lower stair rail.
